Answer:

See below

Step-by-step explanation:

The LHS and RHS are exactly the same, so the equality is true.

The associate property of addition says that

\boxed{a+(b+c)=(a+b)+c}

In order to make the addition of fractions, the denominators should be same. So we can write three fractions as one.

\dfrac{1}{2} +\left(\dfrac{2}{3}+\dfrac{3}{4} \right )

\dfrac{1}{2} +\dfrac{2}{3}+\dfrac{3}{4}

\dfrac{1\cdot 6 }{2\cdot 6} +\dfrac{2 \cdot 4}{3 \cdot 4}+\dfrac{3 \cdot 3 }{4 \cdot 3}

\dfrac{ 6 }{12} +\dfrac{8}{12}+\dfrac{9 }{12}

\dfrac{ 23 }{12}

natita [175]
The equation is just 5 3/4 times 3 1/3. You make the denominators the same by multiplying them by each other. It will be 5 3/12 times 3 1/12. Now you times these two together. You can do this part yourself because it will be confusing on here. I hope i helped atleast a little.
