Answer:
$3.00
Step-by-step explanation:
Setting up an equation with a variable and using key words from the problem will allow you to solve for the sum of money.
'x' = sum money
'nine tenths of a sum' = [tex]\frac{9}{10}x[/tex]
'is 2.70': = 2.70
[tex]\frac{9}{10}x[/tex]=2.70
Multiply both sides by the reciprocal of 9/10 (10/9):
(10/9)(9/10)x = 2.70(10/9)
x = 27/9 = $3.00
The sum of money is 3.
Given
Nine-tenths of a sum a money 2.70.
The addition is the process of adding things together. To add the numbers together, the sign “+” is used.
Let the sum of money be x.
Then,
The equation can be written as;
[tex]\rm \dfrac{9}{10}x=2.70\\\\x=\dfrac{2.70}{9}\times 10\\\\x=\dfrac{27}{9}\\\\x=3[/tex]
Hence, the sum of money is 3.
