The has tank in hana's car holds 15 1/2 gallons. if hana used 3/4 of a tank of gas when she drove across Arizona , how many gallons of gas did she use on that trip
Convert to decimal, multiply, covert back to fraction.
Is it subtraction the problem
No. Your simply trying to figure out what 3/4 is of 15 1/2. Convert to decimal. 15.50 0.75 Multiply. 15.5 * .75 Convert to fraction.
You would subtract if it asked how much she had left
15.5 * .75 = 11.625 11 1/4 would = 11.25
Can u do that in fractions not decmials
0.625 = 5/8. Your answer is 11 5/8 :)
So u would do 15 1/2 equals 31/2 then muiltply that to 3/4 and then get 93/8 then get 11 4/8 simplfy equals 11 1/4 tell me what i did wrong
First, convert the fractions (15 1/2 & 3/4) to decimals. Then multiply the two together. (15.5 * .75) Then convert the decimal to a fraction. (11.625 = 11 5/8)
If you don't want to convert to decimals and back into a fraction you can simply multiply the fractions. Whatever works best for you. Multiplying the fractions: Convert 15 1/2 to a improper fraction. = 31/2 Multiply 31/2 by 3/4. = 93/8 Covert/simplify that into a mixed number. = 11 5/8
