Question

How do you simplify this? Last week, the cost of a tank of gas increased by $1.64. Expressed his increase as a mixed number in simplest form.

Answer 1

A mixed number is a number and a fraction. So we have 1 whole, which is the dollar, but we also have 64 cents. 100 cents make a dollar, so we just have to simplify 64/100.
64/100
32/50
16/25
16/25 is the simplest fraction, so 1 and 16/25 is the correct answer

Answer 2

Oh ok that makes sense thank you!!!!!
