Answer:Jermaine
Step-by-step explanation:
1 1/12
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(1/3, 3/4) = 12
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(13×44)+(34×33)=?
Complete the multiplication and the equation becomes
4/12+9/12=?
The two fractions now have like denominators so you can add the numerators.
Then:
4+9/12=13/12
This fraction cannot be reduced.
The fraction
13/12
is the same as
13÷12
Convert to a mixed number using
long division for 13 ÷ 12 = 1R1, so
1312=1 1/12
Therefore:
13+34=1 11/2
Answer:
40
Step-by-step explanation:
Answer:
<u>372 ft</u>
Step-by-step explanation:
This can be solved through cross multiplication.
310ft/10sec= x/12sec
Multiply the values across from each other. (A good way to know you've done it properly is if the numbers you multiplied are in different measurements. ex: 1 value is feet, the other is seconds)
310 x 12 = 3720
Divide by the remaining value.
3720 / 10 = 372
