Question 1
(a)
- Incorrect use of equals sign. In the answer given it is used to link parts of the solution together, for example: "207 = 207/48" but this is not true mathematically.
- No usage of link words
- Does not include the units of measurement.
(b)
Since we know that 48 stacked buses is equivalent to 207m, to find the size of 1 bus, we divide 207 by 48: \(\frac{207m}{48}=4.3125\) m
we then round to 1 decimal place
\(4.3125\ m=\ 4.3\ m\left(to\ 1\ d.p.\right)\)
Based on this working we know:
\(Bus\ Height\ =\ 4.3\ m\)
Question 2
(a)
We want to find the amount of cream cheese needed for 6 people, we know that for 10 people you need 565 g of cream cheese. We will find the amount needed for 1 person by dividing 565 g by 10
\(\frac{565}{10}=56.5\ g\)
We then multiply the result by 6, since we need to find the amount for 6 people.
\(56.5\ g\ \cdot6\ =339\ g\)
We know that 339 g is the amount of cream cheese needed for 6 people.
