Question

Write a expression for the calculation 84 divided into sevenths added to 9 divided into thirds

Answer 1

(84÷7)+(9÷3) The parentheses are not necessary but I just put them.
I think that's what you meant. If you meant the other thing this would be the equation: (84÷7+9)÷3. Here the parentheses are nessasary

Answer 2

Answer: Our expression is $\dfrac{84}{7}-\dfrac{9}{3}=15$

Step-by-step explanation:

Since we have given that

84 divided into sevenths means

$\dfrac{84}{7}\\\\=12$

9 divided into thirds means

$\dfrac{9}{3}\\\\=3$

Now, 84 divided into sevenths added to 9 divided into thirds means

$12+3\\\\ =15$

Hence, our expression is $\dfrac{84}{7}-\dfrac{9}{3}=15$
