Answer:

$\large{ \tt{☄ \: EXPLANATION}} :$

✎ Firstly , Remember these things :

To convert the percentage into a decimal fraction, remove the % symbol and divide it by 100 as in the case of conversion of percentage into fraction. We know that , divide by 100 means shifting to the left ; so to convert a percentage into decimal fraction, remove the % symbol and shift the decimal point two places to the left. For example : $12\% = \frac{12}{100} = \boxed{ 0.12}$

$\large{ \tt{☥ \: LET'S \: SOLVE}} :$

$\large{1. \: \: 52\% \: \text{of} \: 210 = \frac{52}{100} \times 210 = 0.52 \times 210 = \boxed{109.2} }$

$\large{ 2. \: \: 35\% \: \text{of} \: 500 = \frac{35}{100} \times 500 = 0.35 \times 500 = \boxed{175} }$

$\large{3. \: 28\% \: \text{of} \: 866 = \frac{28}{100} \times 866 = 0.28 \times 366 = \boxed{102.48} }$

$\large{ \tt{✺ \: REPEAT \: DAILY} }:$

I will remain focused on my goals. Even if I have a moment of difficulty , I will not give up. I know Success comes with consistency. I know that I will make it. Things will get better. No problem or challenge will stop me. Everything I deserve is coming my way.

ツ Hope I helped! ۵

Write 1 2/3 as the sum of a whole number and two fractions that have the same denominator.

larisa [96]

1+1/3+1/3 because 1/3 and 1/3 have the same denominator.
