Answer:
4.2
Step-by-step explanation:
Using PEMDAS,
- Parenthesis
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
We know that to solve (3*7) divided by 5, we will need to solve what is in the parenthesis.
So, we need to figure out what is 7*3, which is 21.
This is what we have right now:
21 divided by 5
The next step is dividing,
- We divide 21 by 5 to get 4
- Multiply the quotient digit (4) by the divisor 5
- Subtract 20 from 21
- Add a decimal place and a zero to the dividend, bring down the zero from the dividend
- Divided 10 by 5 to get 2
- Multiply the quotient digit (2) by the divisor 5
- Subtract 10 from 10
- The solution for the division is 4.2
In the end, the answer is 4.2, hope this helped!
