Question

calculează :(4×2):(1+1)=...,(10×2):(1×2)=...(2×7):(2+0)=...(6:2)×(4:2)=....(20:2):(2×1)=..​

Answer 1

$(4 \times 2) \div (1 + 1) = 8 \div 2 = 4$

$(10 \times 2) \div (1 \times 2) = 20 \div 2 = 10$

$(2 \times 7) \div (2 + 0) = 14 \div 2 = 7$

$(6 \div 2) \times (4 \div 2) = 3 \times 2 = 6$

$(20 \div 2) \div (2 \times 1) = 10 \div 2 = 5$
