0.05 mm * ? days = 0.75 inch
Use proportions
1 mm = 0.0394 inch
0.05 mm = 0.00197 inch
0.75 inch / 0.00197 inch = 380.71
380.71 days / 30 days = 12.7 months
Students on the minibus = 8
students that are boys = 5
fraction of the student that are boys = ?
we can write fraction as the numerator and denominator so here the fraction of boys students is = 5/8
this fraction means and shows that there are 5 students are boys from 8 students.
This problem is very simple. All you have to do is add 10 and 9. The correct answer is D.
There are an infinite amount of numbers between 5 and 10 if you consider decimal positions.
However, if you're referring to whole numbers (example: 5, 25, 200, etc)
There are 4 numbers between 5 and 10:
6, 7, 8, and 9.
Well, for 20 you just add them, to get
. For 21, you do a substraction:
. It'd take him quite some time (does this one even have zeros? :)) )
