HELP me please.......? |
HELP MORE QUESTIONS THAT I DONT GET HELP PLEASE.. how many pieces of rope,each 3/8 foot long can be cut from 2 lengths of rope each 3/4 foot long? two cyclist went on separat bicycle rides. the first cyclist traveled 15 miles . if the second cyclist traveled 3/5 as far as the first cyclist. how far did she travel? a seamstress is making several shirts if each shirt requires 3/8 square yard of cloth, how many shirts can she make from 6 square yards of cloth? one thousand five hunderd pounds are what part of one ton?give answer is lowest term. five-sixth of a liter is how many twenty-fourths of liter? add 2/3 yard, 4/9yard , and 23/36 how much larger than 1/4 mile is 9/10 mile? a sporting goods store has 39 bicycles. if 2/3 of this quanitity are sold , how many bicycles were sold? divide 1/3yd.by 9/13yd. 3/8 foot question. 3/8 is half of 3/4. Therefore, each 3/4-foot segment of rope can be cut into two 3/8-foot segments. Since there are two segments of rope initially, when you're done there will be four. Question 1. The second cyclist traveled 3/5 of 15 miles, which is (3/5 x 15) miles. My sixth-grade teacher kept saying over and over that when someone says 3/5 *of* something, it means multiply 3/5 by the other number. Percents work the same way: 7% of 54 is 7 per cent (per 100, or .07) multiplied by 54. Question 2. Shirts: your setup is six divided by 3/8. In late grade school (think this also was sixth grade), someone helpfully said that the way to set these up was. . . . 6 (divided by) 3/8 Change the division sign to a multiplication sign. The 3/8 will be so surprised that it will *flip*, so your problem now looks like 6 x 8/3 Work from there. Question 4. A ton is 2000 pounds. Your setup is 1500 / 2000. Question 5. 5/6 = ?/24. When you change the appearance of a fraction, if you wantt o keep it the same fraction, you have to do the same thing to the top number as you do to the bottom number. What did you do to the bottom number? You multiplied it by 4. 5 times four is. . .. Question 6. 2/3 + 4/9 + 23/36. Your lowest common denominator is 36 (it would be 9, except you have that pesky 36 in there. . .). Anyway. Again, you have to do the same thing to the top number that you did to the bottom number. 2/3 = ?/36 Since you multiplied 3 by 12, you also multiply2 by 12, and your fraction is 24/36. 4/9 = ?/36 Since you multiplied 9 by 4, you also multiply 4 by 4, and you get a truck (or else you get 16, and your fraction is 16/36). Question 7. 9/10 - 1/4 10 = 2 x 5 4 = 2 x 2 The lowest number which is a multiple of 10 and also a multiple of 4 is 20. 9/10=?/20 (you multiplied 10 by 2, so multiply 9 by 2) 1/4=?/20 (you multiplied 4 by 5, so multiply 1 by 5) Question 8. 2/3 of 39. Of means multiply. 2/3 x 39. . . 2/3 x 39 = 2/3 x 39/1. Cross-cancelling works better with a horizontal fraction bar, but we look at the denominator of the first term (number below the fraction line), which is a 3. We look at the numerator (number above the fraction line) of the second term, which is a 39. What goes into 3 evenly and also goes into 39 evenly? That would be 3. Divide both of these numbers by 3 and you get 2/1 x 13/1 = 2 x 13. Two times thirteen is. . . . Question 9. 1/3 yard divided by 9/13 yard. 1/3 (division sign) 9/13 Change the division sign to a multiplication sign. The second fraction is so surprised that it flips: 1/3 x 13/9 Multiply the numerators togethre: 1 x 13 Multiply the denominators together: 3 x 9. Source(s): Sixth- or maybe seventh-grade math. 2 w/e 3/5 of 15 is 12 3/4 20/24 73/36 13/20 w/e 2/3 of 39 is 13/3 Well, since 3/8 is half of 3/4, you can get 2 out of 1 rope, and 4 out of 2. 15 X 3 = 45, 45/5 = 9 miles. 6 total yards / (3/8) = 6 x 8/3 = 48/3 = 16 1500/a ton = 1500/2000= 15/20 = 3/4 24/6 = 4. 5x4 = 20. (2/3)(12/12) = 24/36, 4/9(4/4) = 16/36 24/36 + 16/36 + 23/36 = 63/36, simplify: 7/4 (1/4)x(5/5) = 5/20, (9/10)x(2/2) = 18/20 18/20-5/20 = 13/20 39x(2/3) = 26 (1/3)/(9/13)=(1/3)x(13/9)=13 / 27 |
