13/18 - 4/9=?Simplify 7/6 divided by 3/5 =?Simplify 12 divided by 3/7=Simplify?

Answer 1

Part One;
(13/18) - (4/9) =
you need to do exactly what ma doing ;
18 * 9 = 162
162 / 18 = 9
162 / 9 = 18
so you have ; ( (9*13) - (18*4) ) / 162 = ( 117 - 72 ) / 162 =
45 / 162 ={ you can divide 45 and 162 by 3 so you have :
15 / 54 again divide by 3 so you have 5/18 = 0.27

Part Two;
(7/6) / (3/5)
{ here am going to tell youa trick . just do that if you have
(a/b) / (c/d) = ( a*d) / ( b*c) , means far * far & near * near}

(7/6) / (3/5) = ( 7*5) / ( 6*3) = 35 / 18 = 1.94 bar above 4

Part Three;
12 / (3/7)
imagive you have 12 / 1
so just like part two we should do;
( 12 / 1) / ( 3/7) = (12*7) / (1*3) = 84 / 3 = 28

Its what we are looking for.

Good Luck.

Answer 4

Use a calculator. If you don't have one use your cell phone. If you don't have one use your palm pilot. If you don't have one use a piece of paper and a pencil/pen. If you don't have that use your computer. If you don't have one how did you ask this question.

Answer 5

If this is a home work Q you need to learn to do it on your own. I didn't spend all that time and $$$ getting my MBA to do basic math.

Sorry.
