Step-by-step explanation:
$900 that he gained in December +$500 that he gained in January-$300 that he lost=$1100
A ratio stays equivalent when you multiply or divide the same thing to both numbers, just like fractions:
First of all, you can simplify it to
3:4 by dividing both numbers by 5.
Now you can multiply both numbers by 5 to get 75:100
Finally, you can multiply both numbers by 3 to get the ratio 45:60
If you would like to know about how much will you spend on gas, you can calculate this using the following step:
$3 per gallon & 23 miles for every gallon of gas:
$3 * 23 miles = 69 miles
Result: You will spend $3 for 69 miles.
