Question

a) (5° +51 +52 + 5): 22,
c) (2° +2+2° +2° +3): 22,
b) (7 +7 +7 - 3): 2;
d) (3° + 3'+32 +31-2):2
b)​

Answer 1

$a) \: \frac{52 \times 2 + 5}{22} = \frac{109}{22} \\ b) \: \frac{1 + 2 + 1 + 1 + 3}{22} = \frac{4}{11} \\ c) \: \frac{7 \times 3 - 3}{2} = \frac{6 \times 3}{2} = {3}^{2} = 9 \\ d) \: \frac{60 + 5}{2} = \frac{65}{2}$
