Johannesburg's sister is 54cm tall
Explanation:
3/5 = 0.6
0.6 * 90 = 54
54 is 3/5 of 90, therefore Johannesburg's sister is 54cm tall
Step-by-step explanation:
7y = 9x-27
sub 7x = 9x-27 into 2nd eqn
45 + (9x-27) = 9x
move 9x over
18 = 9x - 9x
18 = 0
this doesn't make sense, so eqn has no solution
Answer:
2/5 is the smallest fraction. Your welcome.
