Consider the enlargement of the pentagon.

1 answer:

5 0

"Enlargement" here implies that the two pentagons are similar. Because of similarity, the following equation of ratios must be true: 7/15 = x/7. Then 15x=49, and x = 49/15 = 3.27 cm, approximately.

Rounded to the nearest tenth, that comes to 3.3 cm.

Solution given:

$2\frac{4}{5}.3\frac{1}{8}$

=2*3* $\frac{4*1}{5*8}$

<h3>=6 $\frac{4}{40}$ </h3><h3>proved </h3>

But I don't think its a. right question.

for more detail look below but answer is above

Solution given:

L.H.S

$2\frac{4}{5}.3\frac{1}{8}$

converting mixed fraction to normal fraction

$\frac{2*5+4}{5}.\frac{3*8+1}{8}$

$\frac{14}{5}.\frac{25}{8}$

over here dot[.] means multiply

now

= $\frac{14*25}{5*8}=\frac{350}{40}$

while

dividing 350 by 40,we get

Quotient=8

remainder=30

In mixed fraction=8 $\frac{30}{40}=8\frac{3}{4}$
