Solve the equation a = m – n for the variable n.

MaRussiya [10]

Answer:

$m - a = n$

Step-by-step explanation:

Step 1: Subtract m from both sides

$a - m = m - n - m$

$a - m = -n$

Step 2: Divide both sides by -1

$(a - m) / -1 = -n / -1$

$-a + m = n$

$m - a = n$

Answer: $m - a = n$

What is 1 3/5 × 2 1/7

MakcuM [25]

Answer:

$\large\boxed{1\dfrac{3}{5}\times2\dfrac{1}{7}=3\dfrac{3}{7}}$

Step-by-step explanation:

Step 1:

Convert the mixed numbers to the improper fractions:

$1\dfrac{3}{5}=\dfrac{1\cdot5+3}{5}=\dfrac{8}{5}\\\\2\dfrac{1}{7}=\dfrac{2\cdot7+1}{7}=\dfrac{15}{7}$

Step 2:

We multiply the numbers remembering about simplifying:

$1\dfrac{3}{5}\times2\dfrac{1}{7}=\dfrac{8}{5\!\!\!\!\diagup_1}\times\dfrac{15\!\!\!\!\!\diagup^3}{7}=\dfrac{8\times3}{1\times7}=\dfrac{24}{7}=\dfrac{21+3}{7}=\dfrac{21}{7}+\dfrac{3}{7}=3\dfrac{3}{7}$
