Learning Task 1: Read and analyze each problem carefully. Write your final answer in your notebook based on the given questions

solmaris [256]

Solving the given problems using the appropriate arithmetic operation such as multiplication, divison and addition, the answers are :

4 people
1000 ml
$1960

Total size of pizza = $2 \frac{2}{3} = \frac{8}{3}$

Number of pizzas gotten by each person = $\frac{2}{3$

Number of people sharing pizza :

$\frac{8}{3} \div \frac{2}{3} = \frac{8}{3} \times \frac{3}{2} = 4 \: people$

2.)

Volume bottle = 600 ml

Fraction of water = $\frac{3}{5}$

Volume of full bottle = $\frac{3}{5} \times n = 600 = \frac{3n}{5} = 600$

Volume of full bottle = $\frac{3n}{3000}$

Volume of full bottle = $n = \frac{3000}{3} = 1000 ml$

3.)

Amount left = Php. 980
Fraction spent = $\frac{4}{8}$

Let the monthly salary = m

Fraction left = $1 - \frac{4}{8} = \frac{4}{8} = \frac{1}{2}$

Hence,

$\frac{1}{2} \times m = 980$

$\frac{m}{2} = 980$

$m = 980 \times 2 = 1960$

Therefore, Joel's monthly salary is $1960
