Answer:
His estimation is correct
Explanation:
First, we will convert the mixed number to fractions as follows:
4[tex] \frac{2}{7} [/tex] = [(7*4)+2] / 7 = [tex] \frac{30}{7} [/tex]
1[tex] \frac{3}{5} [/tex] = [(5*1)+3] / 5 = [tex] \frac{8}{5} [/tex]
Then, we will do the multiplication as follows:
[tex] \frac{30}{7} [/tex] * [tex] \frac{8}{5} [/tex]
= [tex] \frac{30*8}{7*5} [/tex]
= [tex] \frac{240}{35} [/tex]
= [tex] \frac{48}{7} [/tex]
Finally, converting the [tex] \frac{48}{7} [/tex] into a mixed number, we will find that it is equivalent to 6[tex] \frac{6}{7} [/tex]
Hope this helps :)
