Answer:
6. 7.5
5.45 23/132
Explanation:
6. is 7.5
3/4 x 10 or you can put the fraction to a decimal (0.75x10) which is 7.5.
To multiply a fraction you multiply the top numbers (3 x 10) and multiple the bottom numbers (you will put a 1 under the 10) 10/1
3/4 x 10/1
That is 30/4
Then divide.
which would get you 15/2 (that is the simplest form)
To convert a fraction to a decimal, just divide the numerator by the denominator.
__________________________________________________________
To do 5.
Put the fraction in an improper fraction
5 7/12
Just multiply the big number (5) by 12 (the denominator)
67/12
Do the same for 8 1/11
89/11
Now multiply them (I showed how to on number 6.)
67/12 x 89/11
5963/132
Convert that back to a mixed fraction
45 23/132
That's your answer!
(To simplify a fraction)
"You can simplify a fraction if the numerator (top number) and denominator (bottom number) can both be divided by the same number"
Find the same number then divide.
