7/28 as a decimal would be 0.28
Answer:
399 children, 33 adults
Step-by-step explanation:
Children = c
Adults = a
c + a = 432
a = 432 - c
1.5c + 2a = 664.50
1.5c + 864 - 2c = 664.50
-.5c + 864 = 664.50
-.5c = -199.5
.5c = 199.5
c = 399
432 - 399 = 33
a = 33
Of means multiply, so it would be 40% x 64
40% is equivalent to 0.40, so you would use the equation
C. 0.40(64) = n
You distribute the -4 with the -8x and -8 which results in 32x+32.
3/4 is greater than 1/4
Hope I understood correctly for your sake
