  15. Maths challenges

    Bronze

    1) You can uses nine, 5ps to make 45p

    9 * 5 = 45

    2) You can use four, 10p and one, 5p.

    4 * 10 = 40, then add 5 to make 45p

    3) You can use two, 20p and one 5p.

    20 + 20 = 40, then add 5p to make 45p

    4) You can use one, 20p and two, 10p and one 5p.

    20 + 10 + 10 + 5 =45p

    I have found these ways to make 50p.

    1) You can use ten, 5p to make 50p

    5p * 10 = 50p.

    2) You can use five, 10ps to make 50p

    10p + 10p + 10p + 10p + 10p = 50p.

    3) you can use, one 20p, and three, 10ps to make 50p.

    20p + 10p + 10p + 10p =50p.

    Silver

    For Lucy to pay for the ride and only use no more than 3 coins.

    1) she uses, two 5ps and one 10p.

    10p + 5p + 5p = 20p.

    2) she uses, one 10p and one, 2p and one 5p.

    10p + 2p + 5p = 17p.

    Gold

    1) I think there are 9 coins in the first pile and 1 left in the second pile.
    2) I think the third pile has 4 coins, and the second pile has 2 coins.
    3) I think the fourth pile has 8 coins, and the second pile has 4 coins.

    As each coins are moved to relevant piles.

    Platinum

    1) the three coins used to make 27p are

    20p + 5p + 2p = 27p.

    2) the three coins used to make 31p are

    20p + 10p + 1p = 31p

    3) the values of the first coin, double is 40p. The first coin was 20p.

    20p + 20p = 40p
