Question

5•8-16:2= 45-25:5= 80-(23+12):5=

Answer 1

===================================================================

5*8-16:2=40-8=32

25-25:5=25-5=20

80-(23+12):5=80-35:5=80-7=73

Answer 2

Let's solve each of these expressions step by step:

1. 5 * 8 - 16 / 2 First, perform the multiplication and division from left to right: 5 * 8 = 40 16 / 2 = 8 Now, subtract 8 from 40: 40 - 8 = 32

2. 45 - 25 / 5 Again, perform the division first: 25 / 5 = 5 Now, subtract 5 from 45: 45 - 5 = 40

3. 80 - (23 + 12) / 5 First, calculate the sum inside the parentheses: 23 + 12 = 35 Now, perform the division: 35 / 5 = 7 Finally, subtract 7 from 80: 80 - 7 = 73

So, the values of the expressions are as follows:

1. 5 * 8 - 16 / 2 = 32
2. 45 - 25 / 5 = 40
3. 80 - (23 + 12) / 5 = 73
