Can you check these?

.04 is 1/8% of what number? 32

What percent of 1/8 is 3 1/2? 2800%

Why could you not check them??

is (1/8)% of 32 = .04 ??
(1/800)(32
= 32/800
= .04 , so YES

x(1.8) = 3
x = 3/1.8 = 1.6666.. or 166.66..% or 166 2/3%

check that:
take 166.66..% of 1.8
= (166.666../100 )(1.8)
= 3
