All you need to do is add 37+16 and it will be equivalent to 53
I will show you how to do the first one.....we are finding the GCF...the largest number that goes into each number (same for variables)
1.) 20yx , 80x³ ( factor each number and variable)
20 = 2, 4, 5, 10, 20
y = y
x = x
80 = 2, 4, 5, 8, 10, 16, 20, 40, 80
x³ = x, x, x
what is the largest number that 20 and 80 have in common? 20...
how about the variables? x
so, the Greatest Common Factor (GCF is 20x)
10% of the 50 were red.
10% * 50
(10/100) * 50
(1/10) * 50
= 5
5 were red.
5/1 is the reciprocal of 1/5
