3/16+9/10

Let's calculate: $\frac{3}{16}+\frac{9}{10}$

ⓘ To add fractions, put them over the same denominator, then add the numerators. We choose $80$, the least common multiple of $16$ and $10$. Multiplying the numerator and the denominator by the same number does not change the fraction: $\frac{3}{16}+\frac{9}{10}$ = $\frac{3\times 5}{16\times 5}+\frac{9\times 8}{10\times 8}$ = $\frac{3\times 5+9\times 8}{16\times 5}$

$\frac{3\times 5+9\times 8}{16\times 5}$

ⓘ Multiplications are done before additions and subtractions: $3\times 5$ = $15$, $9\times 8$ = $72$

ⅰ $16\times 5$ = $(10+6)\times 5$ = $10\times 5+6\times 5$ = $50+30$ = $80$

$\frac{15+72}{80}$

ⓘ Calculate the numerator and denominator before dividing: $15+72$ = $87$

▶Result:   $\frac{87}{80}$

The numeric value of: $\frac{87}{80}$ is:

▷ $1.0875$
