∙ 14y agoThis can be done in different ways, but it is probably easiest to convert all the mixed fractions to improper fractions first. Then multiply all the numerators, and all the denominators. You can do simplifications either before multiplying, or after multiplying.
It is: 1/4 times 1/5 = 1/20

Because if you are multiplying a number, x, three times it is the formula of multiplying a cube!
4/5x1.17 = 0.94

Three times the fifth root of three.

3q over r to the fourth power
1.2 X 2.25 = 2.7
