Question

Write the length of each insect as a fraction or a mixed number and as a decimal

Answer 1

14.90/100 and .90 15. 1 15/100 and 1.15

Explanation:

each tick equals 10 centimeters so the first one is .90 and the second one is 1.15

Answer 2

15. The length of the insect =
`(7)/(8)` inches

The length of the insect in decimal = 0.875 inches

16. The length of the insect =
`1(1)/(16)` inches

The length of the insect in decimal = 1.0625 inches

Explanation:

We are given the length of the insects in inches scale.

The scale 1 inch divided by 16 equal intervals. (Count the number of small lines between 0 to 1 inch)

14) The insect covers 14 equal parts out of 16 equal parts.

The length of the insect =
`(14)/(16)` inches

We can simplify the fraction
`(14)/(16)` by dividing the numerator and the denominator by 2.

=
`((14)/(2) )/((16)/(2) ) = (7)/(8)` inches

Now let's convert the fraction
`(7)/(8)` to decimal by division.

Dividing 7 by 8, we get

`(7)/(8) = 0.875 inches`

15) Here the insect is more than 1 inches. So the length of the insect is a mixed number.

The length of the insect =
`1(1)/(16)` inches

Now let's convert this to decimal.

Divided the fraction part
`(1)/(16)` and add 1

`(1)/(16) = 0.0625`

So,
`1(1)/(16)` = 1 + 0.0625 = 1.0625 inches
