Sagot :
1) 60 + 48 ÷ 2 × 4 = 156
Following the rule of operations (Multiplication, Division, Addition, Subtraction)
60 + 48 ÷ 2 × 4
60 + 96
Final answer is 156
2) 12 + 5 × 16 ÷ 4 - 7 = 25
Also following MDAS
12 + 5 × 16 ÷ 4 - 7
12 + 20 - 7
Final answer is 25
3) 6 × 7 - 48 ÷ 12 + 75 = 113
Also following MDAS
6 × 7 - 48 ÷ 12 + 75
42 - 4 + 75
Final answer is 113
4) Subtract the quotient of 105 and 5 from 50 = 29
First, convert word sentence to mathematical sentence
50 - ([tex]\frac{105}{5}[/tex])
Since we have a parenthesis, we will use Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction
50 - ([tex]\frac{105}{5}[/tex])
50 - 21
Final answer is 29
5) Add the product of 4 and 56 and the quotient of 845 and 5 = 393
Convert word sentence to mathematical sentence
(4 x 56) + ([tex]\frac{845}{5}[/tex])
Also following PEMDAS
(4 x 56) + ([tex]\frac{845}{5}[/tex])
224 + 169
Final answer is 393
