Answer:
27 ounces of flour
Explanation:
x
=
7/3 = 63/x
isolate the so that it is on the top, so multiply by x on the right and on the left
this gives you:
x*7/3 = 63
try to isolate x and multiply by 3 to get rid of the denominator
x*7 = 63 * 3
x*7 = 189
finally isolate x by dividing by 7 and getting rid of the 7 multiplying with it
x= 189/7
x = 27
you need 27 ounces of flour if you have 63 ounces of sugar
