navik [9.2K]

75% of the teachers were first-year teachers

Step-by-step explanation:

the formula for percentage will be used for the problem

The percentage is given by:

$Percentage=\frac{Quantity}{Total}*100\\$

Here

Total teachers = 57+19 = 76

First-year teachers = 57

So,

$Percentage\ of\ first\ year\ teacher = \frac{57}{76}*100\\=0.75*100\\=75\%$

Hence, 75% of the teachers were first-year teachers

2/5 + 1/4 + 7/10 = what's the answer

kotegsom [21]

Convert 2/5, 1/4 and 7/10 to fractions with like denominators.

$\bf{\dfrac{2\times4}{5\times4}+\dfrac{1\times5}{4\times5}+\dfrac{7\times2}{10\times2} \ \ \to \ \ \ Multiply }$

$\bf{\dfrac{8}{20}+\dfrac{5}{20}+\dfrac{14}{20} }$

Since 8/20,5/20 and 14/20 have the same denominator, add their numerators to add them up.

$\bf{\dfrac{8+5+14}{20} \ \ \to \ \ \ Add. }$

$\green{\underbrace{\red{\boxed{\purple{\boxed{\bf{\blue{\frac{27}{20} }}}}}} \ \ \to \ \ \bf{\red{Answer}}}}$
