Question

What is the product of 4 2/5 and 2 1/7?

Answer 1

first convert into improper fractions:
\[a \frac{ b }{ c }=\frac{ a*c+b }{ c }\]
\[4\frac{ 2 }{ 5 }=\frac{ 4*5+2 }{ 5 }=\frac{ 22 }{ 5 }\]
\[2\frac{ 1 }{ 7 }=\frac{ 2*7+1 }{ 7 }=\frac{ 15 }{ 7 }\]
Now multply:
\[\frac{ 22 }{ 5 }*\frac{ 15 }{ 7 }=\frac{ 22*15 }{ 5*7 }=simplify\]

Answer 2

22*15 = 330 & 5*7 = 35
