Answer:
2/5
Step-by-step explanation:
expressing 1 1/2 in an improper fraction:
1 1/2 = 3/2
Hence
(3/5) ÷ (1 1/2)
= (3/5) ÷ (3/2) (convert divide to multiply by flipping divisor fraction)
= (3/5) x (2/3)
= (3 x 2) / (5 x 3)
= 6/15 (divide both numerator and denominator by 3)
= 2/5
The equivalent fraction of 9/15 would be 3/5.
Answer:
The first two is x=60
Step-by-step explanation:
1.5/90 = 1/x
1.5x = 90 x 1
1.5x/1.5 = 90/1.5
x = 60
5x = x^2 + 4
x^2 - 5x + 4 = 0
(x - 4)(x - 1) = 0
x = 4, 1
(x + 6)^2 = 100
x + 6 = +/1 sqrt100
x + 6 = +/- 10
x = 4, -16
