Find the difference between 7/10 and 14/15
Phantasy [73]

Answer:

the difference between the two fractions is 1/10

Step-by-step explanation:

when solving this problem you must switch the denominators to the same number. in this case thats 30. so 10*3 is 30 and 15*2 is 30. so then we multiply 7*3 to get 21 and 14*2 to get 24. so now we have 21/30 and 24/30, so then we compare. and we end up with 3/30, we simplify the answer to 1/10.

Express 11/4 as a mixed number 11/4=8/4+3/4+2and 3/4
BabaBlast [244]

Answer:

11/4 is an improper fraction. 11/4 as a mixed number is 2 3/4 or 2.75, look below for further information.

Step-by-step explanation:

To change 11/4 (an improper fraction) into a mixed number, we need to the denominator (bottom number) by the numerator (top number).

11 / 4 = 2.75

We can then change the 2.75 into 2 and 3/4. Think of a dollar, how many quarters do you need to make a full dollar? Four, and what is the cost of one quarter? 25 cents. 75 divided by 3 is 25. So we can say that 3/4 is equivalent to the decimal 0.75.

Hope this helped! If it did, please consider making this brainliest! :)
