Today in maths we did Hire purchase and Loans.
Example 1
Loans
£1200 Loan
6 Repayments = £215
Total Repayments =
How much more does the loan cost than the paying cash?
We worked this out by finding the total repayments, and you do this by multiplying 6 by £215.
So the total amount of repayments needed is £ 1290
The loan costs £90 [...]

In todays lesson, we continued direct proporion
Example:
6 bags of bowling balls weigh 15 kg. How many bowling balls would weigh 35 kg?
We find out how much one bag weighs by a simple division: 6/15=0.4
We lay this out in a table: Weight (kg) [...]

In thursdays lesson we discussed direct proportion!!
Direct proportion is when you start off with the price or weight of the amount of some thing:
Price/Lollipop
10p / 1
we then coould be asked wat the price of 5 lollipops would be???
So if one lollipop is 10p then if we use direct proportion we should relise that the [...]

direct proportion is about having a equal proportion
For example:I sell some choclate. 5 pieces for a £1. so  by finding out how much a piece is by dividing 100 by five which equals 0.20p.If i sold 10 pieces it should be £2 pounds because I am selling double the amount of choclate.

what is a highest common factor (h.c.f )? Well a highest common factor is a number that goes into two sets of numbers a single number of times. Example - 8 and 12 the highest common factor would be 4 because it goes into them an exact number of times. Factorizing is when u [...]

hello !
In this leason we learnt about electricity bills and how to find out how much we would have to pay.
EXAMPLE:
Apr-04 Reading- 34436 units  - previous
Jul-04 Reading- 35231 - present
We found out that we had to take away the pervious from the present -
 35231 - 34436 = 795
The first 1100 units where 25 pence each [...]

Today we found out about highest Common Factors
 Example:
The factors of 12 are 1, 2, 3, 4, 6 and 12.
and the factors of 8 are 1, 2, 4, and 8 which means the common factors of 12 and 8 are 1, 2 and 4.
So the Highest Common Factor of 12 and 8 is 4.
because if you [...]
