Question

- 1/2 + 3 1/2Mark answer in the grid. Use the correct place value.

Answer 1

According to the given data we have the following expression to solve:

- 1/2 + 3 1/2

To solve this expression we would have to make the following calculations:

First we would multiply 3 times 1/2

`3\cdot(1)/(2)=(3\cdot\:1)/(1\cdot\:2)`

So, we would get:

`-(1)/(2)+(3)/(2)`
`\text{Next, }\mathrm{Apply\: the\: fraction\: rule}\colon\quad (a)/(c)+(b)/(c)=(a+b)/(c)`
`So,\text{ }-(1)/(2)+(3)/(2)=(-1+3)/(2)`
`\mathrm{Add\: the\: numbers\colon}\: -1+3=2`

So, Finally we would get the fraction 2/2 that would be equal to 1.

Therefore, - 1/2 + 3 1/2=1
