Given:

John had to pay a combined electric and gas bill $150.

The electric portion of the bill was $90.

To find:

The ratio of money spent on electric to that on gas.

Solution:

Let x be the amount of gas bill.

The electric portion of the bill was $90 and John had to pay a combined electric and gas bill $150.  So,

90+x=150

x=150-90

x=60

The gas portion of the bill was $60.

The ratio of money spent on electric to that on gas is:

\text{Required Ratio}=\dfrac{\text{Electric bill}}{\text{Gas bill}}

\text{Required Ratio}=\dfrac{90}{60}

\text{Required Ratio}=\dfrac{3}{2}

\text{Required Ratio}=3:2

Therefore, the ratio of money spent on electric to that on gas is 3:2.
