Question

Could someone please help me? Quick cause it's a timed worksheet thingy...

7 2/9 - 5 5/7

Give your answer as a mixed number with fractional part in lowest terms.

Answer 1

Convert the fractions into decimals.
2 / 9 = 0.22
5 / 7 = 0.7

7.22 - 5.7
1.52

Convert that into a fraction
1 52/100
Simplify
1 15/23

Answer 2

@TrashMan914 that isn't right I just tried it, and @hero yep that is the equation

Answer 3

so could you help me with the answer it's timed and it's ticking away lol sorry

Answer 4

well, i would first convert both numbers into improper fractions

then determine the GCD of the 2 fractions (GCd being 63)

convert both fractions so that they have the GCD, then subtract

Answer 5

or if you want to do it as a mixed number,
first carry the 1 over because 2/9-5/7 would result in a negative number
giving you 11/9-5/7
then find GCD
convert fractions

just subtract the fractions
then subtract the whole numbers

Answer 6

oh was it LCM?

i get GCD and LCM mixed up
