Question

Estimated answer for 3 3/7 x 1 3/4

Answer 1

First, rewrite both numbers as improper fractions.

`3(3)/(7)=3+(3)/(7)=(3\cdot7)/(7)+(3)/(7)=(21)/(7)+(3)/(7)=(24)/(7)`
`1(3)/(4)=1+(3)/(4)=(1\cdot4)/(4)+(3)/(4)=(4)/(4)+(3)/(4)=(7)/(4)`

Next, multiply both numbers. To do so, multiply the numerators and denominators sparatedly:

`3(3)/(7)*1(3)/(4)=(24)/(7)*(7)/(4)=(24\cdot7)/(7\cdot4)`

Since the factor 7 appears both in the numerator and the denominator, we can cancel it out:

`3(3)/(7)*1(3)/(4)=(24\cdot7)/(7\cdot4)=(24)/(4)`

Since 24 divided by 4 is 6, then:

`3(3)/(7)*1(3)/(4)=6`
