Answer:
1. 3 1/2
2. 3/4
3. 3 1/3
4. 2/15
5. 6
Step by step explanation:
1. the number 4 here can be written as a fraction
4 = 4/1
Therefore,
we multiply 7 by 4 (numerator by numerator)
and 8 by 1 (denominator by denominator)
= 28/8
= 3 4/8
= 3 1/2
2. we multiply 15 by 4 (numerator by numerator)
and 16 by 5 (denominator by denominator)
= 60 / 80 (in order to simplify, divide by 10)
= 6/8 (we can simplify this fraction further by dividing by 2)
= 3/4
3. subtract 3 from 3 3/5
= 3/5
then multiply numerator by numerator
and denominator by denominator
= 15 / 45
= 1/3
then you add 3 back
= 3 1/3
4. multiply numerator by numerator
no need to simplify
5. 21 x 2/7 = (21 x 2) ÷ 7
= 42 ÷ 7 = 6
Thank you!
God bless!
Have a nice day!
Pls brainliest thx!
