martin has 15 texts messages on his phone .Two thirds of them are from his sister how many texts does martin have from his sister?
I need three different ways to calculate this answer?

Respuesta :

15/3=5. 5x2=10. 2/3=66.66%. 10%=1.5 5%=0.75 1%=0.15 0.66 rounds to 1 1.5x6=9. 9+0.76+1.5+1.5=10. 2:3=10:15.
Divide 15 by 3 and add that number to itself

Multiply 15 by (2/3) (don't forget parentheses if you are using a calculator)

Draw a pic and shade in two thirds
