There are 104 coins in a bottle 1/2 of the coins are £1 coins the rest of the coins are 20p coins work out the total value of the 104

£62.4

Step-by-step explanation:

There are 104 coins in a bottle 1/2 of the coins are £1 coins

Hence:

1/2 × 104 coins = 52 coins

Since 1/2 of the coins are £1 coins

Hence

52 coins = £52

The remaining the rest of the coins are 20p coins

The rest = 1/2 of 104 coins = 52 coins

Note that:

100 pence = 1£

Hence:

100p = 1 £

20p = x

Cross Multiply

100p × x = 20p × £1

x = 20p × £1 /100p

x = £0.2

So, one 20p coin = £ 0.2

Hence:

one 20p coin = £ 0.2

52 20p coins = x

Cross Multiply

x = 52 × £0.2

x = £10.4

The total value for the 104 coins is

= £52 + £10.4

= £62.4

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
