60% of a sum of money is \$120.00.calculate 40% of the same sum ofmoney? ​

In word (story) problems, the word "of" usually means multiply.

We may write 60% or 60/100 or 0.60 as needed   (similar for 40%).

Let x = the sum of money

Translate:

"60% of a sum money is \$120"    means

(60/100)*x             =  \$120

math:

(60/100)*x = \$120

x = \$200              [multiply both sides by (100/60)]

Translate again:

"Calculate 40%of the same sum of money"   means

(40/100)*(\$200)

I like (60/100) and (40/100), you might want to do again using 0.60 and 0.40.

If 60% is \$120, then by diving both the percent and the balance by 3, we se that 20% is \$40.

Now multiply the 20% and \$40 by 2, and you see 40% is \$80.

\$ 80

Step-by-step explanation:

60% of a sum of money is 120

let x represent the sum of money

turn ur percent to a decimal

0.60x = 120

x = 120/0.60

x = 200 this is the sum of money

so 40% of 200 = 0.40(200) = \$ 80 <
