It all about knowing how to estimate decimal
😁😀😎
I'll be glad to check your answers.
180.8/6=180/6=30
18.2/11=20/10=2
55/10.7=50/10=5
0.6/5=1.0/5=0.2
145/0.3=145/3=15
60/5.9=60/6=10
1.8/20=2.0/20=0.1
Right,
To find the quotient for these divisions, you can use long division or a calculator. However, if you prefer to use the "compatible numbers" method, you can follow these steps:
Step 1: Identify compatible numbers. Compatible numbers are close to the given numbers and are easy to divide mentally. Look for whole numbers or multiples of 10 that are close to the given numbers.
Step 2: Divide the compatible numbers. Divide the compatible number you have chosen by the divisor.
Step 3: Adjust the quotient. Multiply or divide the quotient from step 2 by the same factor you used to get the compatible number in step 1.
Let's find the quotient using the compatible numbers method for each division:
1. 180.8 divided by 6:
Compatible numbers: 180 is close to 180.8, and it is divisible by 6.
Divide 180 by 6: 180 ÷ 6 = 30.
Adjust the quotient: Multiply 30 by the same factor used in step 1 (10).
Final answer: 180.8 ÷ 6 is approximately 308.
2. 182 divided by 11:
Compatible numbers: 176 is close to 182, and it is divisible by 11.
Divide 176 by 11: 176 ÷ 11 = 16.
Adjust the quotient: Multiply 16 by the same factor used in step 1 (10).
Final answer: 182 ÷ 11 is approximately 160.
3. 55 divided by 10.7:
Compatible numbers: 50 is close to 55, and it is divisible by 10.
Divide 50 by 10: 50 ÷ 10 = 5.
Adjust the quotient: Multiply 5 by the same factor used in step 1 (10).
Final answer: 55 ÷ 10.7 is approximately 51.4.
4. 117.8 divided by 0.12:
Compatible numbers: 120 is close to 117.8, and it is divisible by 0.12.
Divide 120 by 0.12: 120 ÷ 0.12 = 1000.
Adjust the quotient: Divide 1000 by the same factor used in step 1 (10).
Final answer: 117.8 ÷ 0.12 is approximately 10000.
5. 0.6 divided by 5:
Compatible numbers: 0 is close to 0.6, and it is divisible by 5.
Divide 0 by 5: 0 ÷ 5 = 0.
Adjust the quotient: Multiply 0 by the same factor used in step 1 (10).
Final answer: 0.6 ÷ 5 is approximately 0.
6. 145 divided by 0.3:
Compatible numbers: 150 is close to 145, and it is divisible by 0.3.
Divide 150 by 0.3: 150 ÷ 0.3 = 500.
Adjust the quotient: Divide 500 by the same factor used in step 1 (10).
Final answer: 145 ÷ 0.3 is approximately 50.
7. 60 divided by 5.9:
Compatible numbers: 60 is close to 59, and it is divisible by 5.
Divide 60 by 5: 60 ÷ 5 = 12.
Adjust the quotient: Multiply 12 by the same factor used in step 1 (10).
Final answer: 60 ÷ 5.9 is approximately 120.
8. 1.8 divided by 20:
Compatible numbers: 2 is close to 1.8, and it is divisible by 20.
Divide 2 by 20: 2 ÷ 20 = 0.1.
Adjust the quotient: Divide 0.1 by the same factor used in step 1 (10).
Final answer: 1.8 ÷ 20 is approximately 0.01.
Remember, compatible numbers provide a quick estimation, and the final answers obtained using these numbers may not be entirely accurate.
