Practice makes perfect

Before we evaluate the expression, let's first rewrite the mixed number as fractions.

4 23* 9/10

a bc=a* c+b/c

4* 3 +2/3*9/10

Multiply

12+2/3*9/10

14/3* 9/10

When we multiply fractions, we need to remember that the product of two fractions is equal to the product of the numerators divided by the product of the denominators. Let's find the given product!

14/3* 9/10

14* 9/3* 10

Multiply

126/30

The quotient is 12630. We can also write this fraction as a mixed number because the numerator is greater than the denominator.

126/30
