Answer:
15
Step-by-step explanation:
Fiona (F) = Sushi (S)
Malachy (M) = 7 Fiona (F)
M = F + 90
F + 90 = 7F
6F = 90
F (Fiona) = 15
S (Sushi) = 15
check: Malachy (M) = 15 * 7 = 105
M-F = 105 - 15 = 90
FRACTION: 10 (10 OVER 256)
__
256
3 x 3 is 9, plus 1 is 10
4x4 is 16, and 16² is 256
When you solve these two equations, you end up with the same answer of 1/16 or 0.0625
The answer is negative 2
23/15
