Answer:

3 .1 /2 = 3.50 = 350 %

Step-by-step explanation:

To convert a fraction into decimal, one needs to transform it so that the fraction is a sum of fractions each or which has a denominator, which is a power of 10.

3 .1/ 2 = 3 1 × 50 /2 × 50 = 3 .50 /100 = 3.50

And for conversion to percentage, one needs to multiply this by

100

Hence

3 .1/ 2 = 3.50 = ( 3.50 × 100 )% = 350 %

hope it helps!

Sara has 24 sweets

Tresset [83]

<h2>Hello!</h2>

The answer is:

The expression for the number of sweets that Sara and Tim have now, are:

$Sara=(17-x)Sweets\\\\Tim=\frac{(24+x)Sweets}{2}$

To write the expressions for the number of sweets that Sara and Tim have now, we need to follow the next steps:

Sara starts with 24 sweets and Tim starts with 24 sweets

$Sara=24 Sweets\\Tim=24 Sweets$

Then, Sara gives Tim x Sweets

$Sara=(24-x)Sweets\\Tim=(24+x)Sweets$

Then. Sara eats 7 of her Sweets

$Sara=(24-x-7) Sweets\\Sara=(17-x )Sweets\\Tim=(24+x) Sweets$

Then, Tim eats half of his sweets

$Sara=(17-x)Sweets\\\\Tim=\frac{(24+x)Sweets}{2}$

So, the expression for the number of sweets that Sara and Tim have now, are:

$Sara=(17-x) Sweets\\\\Tim=\frac{(24+x)Sweets}{2}$

deff fn [24]

12 girls out of 30 were selected, so the ratio "selected:tried" if 12/30. This fraction can be simplified into

$\dfrac{12}{30} = \dfrac{2}{5}$

Similarly, 16 boys out of 40 were selected, so the ratio "selected:tried" if 16/40. This fraction can be simplified into

$\dfrac{16}{40} = \dfrac{2}{5}$

So yes, the ratio of the number of students on the team to the number of students trying out the same for both boys and girls
