Question

Kim ate 3/10 of a bag of potato chips, sandyaye 3/7of a bag and jeff ate 3/9 of a bag who ate the most kim jeff or sandy

Answer 1

Sandy. You take 3/10 and make it a decimal and that gives you .3 3/7 gives you .4 and 3/9 gives you .3.

Answer 2

Sandy ate more.

Explanation:

Kim ate
`(3)/(10)` of a bag .

Sandy ate
`(3)/(7)` of a bag.

Jeff ate
`(3)/(9)`of a bag

Take the lcm of denominators

LCM of 10,7 and 9 is 630

Make the denominators of fractions same

`(3 * 63)/(10 * 63)=(189)/(630)`

`(3 * 90)/(7 * 90)=(270)/(630)`

`(3 * 70)/(9 * 70)=(210)/(630)`

So,
`(189)/(630)<(210)/(630)<(270)/(630)`

`(3)/(10)<(3)/(9)<(3)/(7)`

So, Sandy ate more.
