2.16=?2, point, 1, start overline, 6, end overline, equals, question mark

Otrada [13]

Answer:

$2\frac{4}{25}$

Step-by-step explanation:

The question asks:

2.16 = ???

The is a decimal number that can be converted to a mixed fraction

2.16 = 2 + 0.16

2 = whole number.

So, we are left with 0.16

We can convert this to a fraction

Since it is in 2 decimal places we Multiply by 100

=( 0.16 × 100)/ 100

= 16/100

We simplify this fraction and we have

= 4/25

Therefore,

2.16 = 2 + 0.16

2.16 = 2 + 4/25

2.16 = $2\frac{4}{25}$

What number should be added to 7/12 to get 4/15?

DENIUS [597]

Answer:

Step-by-step explanation:

Let the number = x.

We are trying to find out what number (x) we would need to add to 7/12 to get 4/15

$\frac{7}{12} + x = \frac{4}{15}$

Subtract 7/12 from both sides.

$x = \frac{4}{15} - \frac{7}{12}$

We need to make the denominators of the fractions the same.

$\frac{4}{15} = \frac{16}{60}$

$\frac{7}{12} = \frac{35}{60}$

So,

$x = \frac{16}{60} - \frac{35}{60} = - \frac{19}{60}$
