c
Step-by-step explanation:
i done it and it c
To multiply fractions, you multiply numerator with numerator and denominator with denominator
In other words: a/b*c/d=(a*c)/(b*d)
So 1st one is (5*2)/(6*3) which is 10/18 or 5/9 simplified
2nd one is (9*5)/(10*18) which is 45/180 or 1/4 simplified
3rd one is (4*3)/(5*4) which is 12/20 or 3/5 simplified
4th one is (2*5)/(3*1) which is 10/3 or 3 1/3 if you want a mixed number
Hope this helped!
Answer:
x=10
5x=50
2x=20
Step-by-step explanation:
110+5x+2x = 180 combine like terms and move the constants to the same side
7x=70
x = 10
5(10) = 50
2(10) = 20
I think is the top one!!!!!!!
