What is 3.125 − 1.6 ? (1 point)
The difference between 3.125 and 1.6 is 1.525.
To find the difference between 3.125 and 1.6, subtract 1.6 from 3.125:
3.125 - 1.6 = 1.525
To calculate 3.125 - 1.6, you need to subtract 1.6 from 3.125.
Here's how you can do it:
Step 1: Write down the numbers vertically, with the decimal points aligned:
3.125
- 1.600
Step 2: If the number on the right (1.600) has fewer decimal places than the number on the left (3.125), add zeros to the right of the number on the right until both numbers have the same number of decimal places:
3.125
- 1.6000
Step 3: Start subtracting the numbers from right to left, starting with the decimal places:
- Subtract the number in the ones place (5 - 0 = 5)
- Then subtract the number in the tenths place (2 - 0 = 2)
- Finally, subtract the number in the hundredths place (1 - 6 = -5)
Step 4: Since we have a negative result in the hundredths place, we need to borrow from the tenths place. So, we can convert 2 tenths to 10 hundredths. Now we can subtract properly:
- Subtract 10 hundredths from 11 hundredths (11 - 10 = 1)
- Subtract 1 tenth from 1 tenth (1 - 1 = 0)
- Subtract 2 ones from 3 ones (3 - 2 = 1)
Step 5: Write down the result:
3.125 - 1.6 = 1.525
Therefore, the difference between 3.125 and 1.6 is 1.525.
