(B) units

(C) one -tenth

(D) one-hundredths

Answer 1

Hint: We have the number 17.5. The number 17.5 has a decimal point. In a decimal point number, the unit digit starts from the first left digit next to the decimal point. Now, use this and get the place value of 7 in the number 17.5

Complete step-by-step answer:

According to the question, it is given that we have the number 17.5 and we have to find the place value of 7 in the number 17.5.

We know that place value is the value of where a digit lies in the given number. 

We have 17.5 as the number and we have to find the place value of 7 in this number.

The number 17.5 has three digits that are 1,7 and 5. We have a decimal point in the number 17.5.

The number 5 is beyond the decimal point in the number 17.5, so the place value of 5 is one- tenth. It means 5 is at one-tenth’s place.

The number 7 is just next to the decimal point in the number 17.5, so the place value of 7 is units. It means 7 is at the unit’s place.

The number 1 is just next to 7 in the number 17.5. Since the place value of 7 is unit, So the place value of 1 is tens. It means 1 is at the tens place.

Therefore, the place value of 7 in 17.5 is units.

Hence, the correct option is (B).

Note: Since the given number 17.5 has three digits that are 1, 7, and 5 so, one might think of a 3-digit number and conclude the place value of 7 as tens. This is wrong because the number has a decimal point too and in a decimal point number the unit place starts from the first left digit next to the decimal point.
