Ответ:
7 1/4
Step-by-step explanation:
Multiply the denominator of 1/2 to equal the denominator of 3/4.
3/4 + 2/4 = 1 1/4.
4 + 2 = 6.
6 + 1 1/4 = 7 1/4.
Ответ:
convert it to improper fractions first
4 3/4
multiply the whole number by the denominator
4*4 = 16
then add the numerator
16+3 = 19
so 4 3/4 = 19/4
apply the same concept to 2 1/2 to get 5/2
now add them
19/4 + 5/2
common denominator = 4
multipky the second fraction’s numerator and denominator by 2
5*2 = 10
2*2 = 4
5/2 = 10/4
now add
19/4 + 10/4 = 29/4
which you can convert back to a mixed fraction by dividing to the nearest whole number
4*7 = 28
which leaves 1/4
29/4 = 4 1/4
Ответ:
4*y=13
4*3=12+1. 4/4=1
20/4 = 5 so 5=1 so y=5
3*20 = 60
60+5=65
Hope that helped!!
