(i) How many students have a height of less than 140 cm?
(ii) How many students have a height equal to or greater than 140 cm but less than 155 cm?
(i) Number of students having height less than 140 cm = 6 + 9 + 20 = 35
(ii) Number of students having height equal to or greater than 140 cm but less than 155 cm = 18 + 16 +12 = 46

Solve for b algebraically (doing the same to both sides)
9b + 15 = 60
9b + 15 -15 = 60 - 15
9b = 45
9b/9 = 45/9
b = 9

What is 5/8 ÷3/24? Work it out twice showing you know BOTH the methods for dividing fractions.
Method 1 - keep, change, flip
Method 2 - same denominator
It is 5.
Method 1 - 5/8 x 24/3 = 120/24 = 5
Method 2 - Triple the first fraction to make the same denominator 15/24 ÷3/24 = 15/3 =5
