Maria, Carolina and Pedro receives $1600 from their grandfather in ratio 7:5:4. calculate share of each. ​

1 : 6 = 2 : 12

The ratio is already in lowest terms so we found an equivalent ratio by multiplying both terms by 2.

Step-by-step explanation:

here's your solution

=> total money received by them = $1600

=> the given ratio are 7:5:4

=> let the ratio be X ,now

=> Maria = 7X

=> Carolina = 5X

=> Pedro = 4X

=> we know whole money = $1600

=> so, adding all

=>. 7x + 5x + 4x = $1600

=> 16x = $1600

=> x= $1600/16

=>. x = $100

now Maria = 7*100 = $700

Carolina = 5*100 = $500

Pedro = 4*100 = $400
