Cheryl solved a problem: 84 ÷ 0.01 = 8,400.
Alexandra [31]

Answer:

Cheryl is correct.

Step-by-step explanation:

Cheryl solved a problem : 84 ÷ 0.01 = 8,400.

This is absolutely right.

When we divide any whole number with the divisor having decimal, we change the divisor to a whole number before performing the division.

To do this, we multiply both the numbers (divisor and dividend) by the same power of 10, until the divisor is a whole number.

\frac{84\times 10}{0.01\times 10} = \frac{840}{0.1}

to make divisor a whole number we will again multiply both the numbers by 10.

\frac{840\times 10}{0.1\times 10} = \frac{8400}{1} = 8,400

Now answer would be 8400.

Therefore, Cheryl is correct.

lozanna [386]

Answer:

2800m

Step-by-step explanation:

Assumption:

Start point from which Percy Cod walks is "x"

If he walks around a perimeter that is the shape of a rectangle,

Length of area = L = 1000m

Width of area = W = 400m

Distance around the rectangle = D = 2 * (L + W)

D = 2 * (400+1000)

D = 2 * 1400

D = 2800m
