Answer: 1x1 + 1x.1 + 8x.01 +6x.001
Step-by-step explanation:
Start from left to right.
The first digit is one, in the ones place. Therefore, your value is one, and your multiple in terms of tens will also be one.
The second digit is also one, but this time it's in the tenths place. Therefore, you're going to multiply it by one tenth, or 0.1
The third digit is eight, and it's in the hundredths place. So, you're going to take eight, and multiply it by one one hundredth, or 0.01
The final digit is six, in the thousandths place, so, following the trend of the previous numbers, you're going to multiply six by one one thousandth, or 0.001
