After completing a fraction division problem, Clarice used multiplication to check her answer. Division: 73 = 11 - 5 Check: 5 x 1 1 / 2 = 5 1 / 1 Could Clarice verify her answer? Explain.

Sagot :

To check the answer you multiply the quotient of the division ( 5 ) by the divisor ( 1 1/2) and this multiplication needs to be equal to the dividend (7 1/2).

To multiply a whole number by a mixed number multiply first the whole number for the whole part of the mixed number, then multiply the whole number by the fraction part of the mixed number:

[tex]5\cdot1\frac{1}{2}=5\frac{5}{2}[/tex]

Simplify it:

[tex]5\frac{5}{2}=7\frac{1}{2}[/tex]

Then, as Clarice did the multiplication and get a wrong product (she doesn't multiply mixed number corretly) , she cannot verify her answer.
