Monique made several batches of soup.
const2013 [10]

Answer:

8 batches

As a batch its a whole number as the multiplier will usually be the fraction

and fraction / fraction should always show fraction but the whole number given with a remainder can be shown if not a whole number.

Step-by-step explanation:

6 1/2 = 6.5

and ;

3/4 of a pound = 0.75  of 1 pound

6.5 / 0.75 = 8.7         or in full workings write = 8.6666.....7

8.7/ 1 = 8 batches with 0.7 or 0.66667 left over

Answer In fraction for exam question given in fraction  8.7 = 8  batches

with  7/10 left over.

The area of a quarter circle is 19.625 square kilometers. what is the quarter circle's perimeter?
liubo4ka [24]

a quarter of a circle is 19.625

 so the area of full circle is 19.625 x 4 = 78.5 sq. km

area of a circle is PI x r^2

78.5 = 3.14 x r^2

78.5/3.14 = 25 = r^2

r = sqrt(25) = 5

radius is 5 km

circumference ( perimeter) = 2 x PI x r

2 x 3.14 x 5 = 31.4 km

 perimeter is 31.4 km
