​

Answer 1

a)

$(6 + 5) \times 9 = (11) \times 9 = 99$

b)

$9 \times (7 + 3) = 9 \times (10) = 90$

c)

$(32 - 4) \div 7 = (28) \div 7 = 4$

d)

$17 \times (5 - 2) = 17 \times (3) = 51$

e)

$(6 + 8) \times (10 - 5) = (14) \times (5) = 70$

f)

$(32 - 10) \times (20 - 15) = (22) \times (5) = 110$

g)

$(9 \times 6) \div (3 \times 9) = (54) \div (27) = 2$

h)

$(6 + 9) \times (32 \div 4) = (15) \times (8) = 120$

I)

$(11 - 4) \times (45 \div 9) = (7) \times (5) = 35$

j)

$35 \div (15 - 10) = 35 \div (5) = 6$
