2 1/2+ 4 2/3 what is it????

Marina86 [1]

Let's first add the whole numbers:

2 + 4 = 6

The LCD of 1/2 and 2/3 is 3/6 and 4/6 . . .

3 + 4 = 7

(The denominators are equal in both fractions so they will remain the same)

= 7/6

Simplifying 7/6 . . .

7/6 = 1 1/6

6 + 1 = 7

7 + 1/6 = 7 1/6

<h3>7 1/6 ← answer</h3><h3 />

<u>Your final answer is 7 1/6.</u>

I hope this helps! :)

All the pupils at a primary school come from one of three villages: Elmswell, Haughley or Woolpit. 1/4 of the pupils come from E

Jlenok [28]

Answer:

Step-by-step explanation:

Given that:

All the pupils at a primary school come from one of three villages: Elmswell, Haughley or Woolpit.

$\frac{1}{4}$ of the pupils come from Elmswell

$\frac{3}{5}$ of the pupils come from Haughley

102 pupils come from Woolpit.

To find:

Total number of pupils in the school.

Solution:

Let total number of pupils = $100x$

So, number of pupils that come from Elmswell = $\frac{1}{4}$ of 100x

$\dfrac{1}{4} \times 100x\\\Rightarrow 25x$

And, number of pupils that come from Haughley= $\frac{3}{5}$ of 100x

$\dfrac{3}{5} \times 100x\\\Rightarrow 60x$

Number of pupils that come from Woolpit = $100x - 25x - 60x \Rightarrow 15x$

As per given statement:

$15x = 102\\\Rightarrow x =6.8$

Number of pupils from Elmswell = 25x = 25 $\times$ 6.8 = 170

Number of pupils from Haughley = 60x = 60 $\times$ 6.8 = 408

Total number of pupils at the school = $100x \Rightarrow 100 \times 6.8=680$
