Daniela painted a photo that was 4/5 afoot by 1 7/8 of afoot. What was the area?

Ahat [919]

Answer:

$\frac{3}{2}$ square feet

Step-by-step explanation:

The dimensions of the photo is 4/5 by 1 7/8 of a foot.

But,

1 7/8 = $\frac{15}{8}$ feet

So that,

length of the photo = $\frac{15}{8}$ feet

width of the photo = $\frac{4}{5}$ feet

The area of the photo = length x width

= $\frac{15}{8}$ x $\frac{4}{5}$

= $\frac{60}{40}$

= $\frac{3}{2}$

Area of the painted photo is $\frac{3}{2}$ square feet.

How to solve this equation?

Sholpan [36]

To solve these type of problems is to simply invert the number after the division sign and multiply

$2 * \frac{7}{2} = \frac{2}{1} *\frac{7}{2} = \frac{2*7}{1*2} = \frac{14}{2} = 7$
