Answer 2

Answer:

Step-by-step explanation:

BODMAS:Bracket, Order, Division, Multiplication, Addition, and Subtraction

1) What is the sum of 1/3+1/2

Sol: 1/3=0.33333333333

       1/2=0.5

      1/3+1/2 = 0.33333333333+0.5

        =0.83333333333 or 0.83 bar

2)What is 70% of 1.25

Sol:Percent (%)' means 'out of one hundred':

1.25% = 1.25 'out of one hundred',

p% is read p 'percent',

1.25% = 1.25/100 = 1.25 ÷ 100.

Calculate percentage:

'Percentage' is obtained by multiplying 70 by 1.25%.

1.25% × 70 =

(1.25 ÷ 100) × 70 =

(1.25 × 70) ÷ 100 =

87.5 ÷ 100 =

0.875 ≈

0.88;

Proof.

How do we check the result?

If 1.25% × 70 = 0.875 =>

Divide 0.875 by 70...

... And see if we get as a result: 1.25%.

Note:

100/100 = 100 ÷ 100 = 100% = 1

Multiply a number by the fraction 100/100,

... and its value doesn't change.

n/100 = n%, any number.

Calculate the percent value:

0.875 ÷ 70 =

0.0125 =

0.0125 × 100/100 =

(0.0125 × 100)/100 =

1.25/100 =

1.25%

3)Simplify 1/2+1/3-1/4 (using BODMAS)

sol: 1/2=0.5

      1/3=0.3 bar

      1/4=0.25

1/2+1/3+1/4=0.5+0.3 bar+0.25=1.08333333333
