Answer:
135 = 3y + 3r
y = 30; r = 15
Step-by-step explanation:
y = 3y + 3r
Where,
y = total number of flowers in the garden = 135
y = number of flowers in each yellow flower bed = 30
r = number of flowers in each red flower bed
135 = 3(30) + 3r
135 = 90 + 3r
135 - 90 = 3r
45 = 3r
r = 45/3
r = 15 flowers
number of flowers in each red flower bed = 15
7/15 / (3/5)
Flip the 2nd fraction and multiply:
7/15 * 5/3
Multiply the numerators and denominators together:
35/45
Divide 5 to the numerator and denominator:
35 / 5 = 7
45 / 5 = 9
7/9
