Answer:
48 sweets
Step-by-step explanation:
5:2:4
Sarah: 5
Natasha:2
Richard:4
To find out how many sweets Richard got, we need to use 60 as the lcm. Since, we have a definite constant of 60 we need to divide it by the presiding ratio.
60/5 = 12
That means for a ratio of 1, everyone in the group recieves 12.
Now, we plug it in for each of the members.
5x = Sarah
2x = Natasha
4x = Richard
Sarah = 60 sweets
Natasha = 24 sweets
Richard = 48 sweets

A. It is a parallelogram so, the formula is just simple base × height; 16cm × 9cm = 144cm²
B. It is a trapezoid so, the formula is base1 + base2 ÷ 2 × height; 25cm+ 44.67cm= 69.67cm ÷ 2 = 34.835cm × 20cm= 696.7cm²
C and D are irregular shapes - the diagram will show you how to do them...
Look at the exponent and move the decimal that many places ( to the right for a positive number and to the left for a negative number)
