100+720
To subtract fractions, we need an lcd( lowest common denominator)
8. the lcd is 42 because it’s the smallest number that 6 and 7 are both factors of. the lcd is the bottom of the fraction
to make the denominator of (4/7) 42, we will multiply the top and bottom by 6 and we get (24/42)
to make the denominator of (3/6) 42, we will multiply the top and bottom by 7 and we get (21/42)
these two numbers now have the same denominator so we subtract them
24/42 - 21/42 = 3/42 which simplifies to 1/14
9. since these fractions already have a common denominator, we will make them mixed fractions
-5(2/7) as a mixed fraction. first multiply 5*7 which is 35. now add 2 which is 37. our mixed fraction is -37/7
-1(5/7) as a mixed fraction. multiple 1*7 which is 7. now add 5 which is 12. our mixed fraction is -12/7
now subtract (-37/7) - (12/7) and we get -49/7 which simplifies to -7

she uses the same amount of fruit so Susan used 5 strawberries per cup ( 5*5 = 25 total strawberries) and 3 kiwi ( 3*5 = 15 total kiwis)
25+15 = 40 total pieces of fruit.
Joanna made 4 cups with 8 strawberries each
8*4 =32
40-32 = 8 , so she can use 8 kiwis
8 kiwis / 4 cups = 2 kiwis per cup
