For Q1, we can start out by turning it into a plain fraction. 16*2=32, and 32+1=33, so 16+1/2=33/2. Similarly, for 2 3/4, 2*4=8 and 8+3=11, so 2 3/4=11/4 as the size of each piece of wood. To divide them, we have the numbers 33/2 and 11/4. We first find the reciprocal of the size of a piece (switch the numerator and denominator) and then multiply the 2 fractions - 33/2*4/11=132/22=6 pieces. Using that, I challenge you to do Q2 on your own!
Answer:
a(b + c) = ab + ac
Step-by-step explanation:
It is the longest side
it is opposite the right angle
One pound = $0.65
Total cost = c
Number of pounds to ship = p
Part a:
c = 0.65p
When p = 2
c= 0.65(2)
c = $1.30
Part b:
One pound = $0.65 - $0.05 = $0.60
c= 0.6p
------------------------------------------------
Answer: (a) $1.30 (b) c= 0.6p
