i really do not get this question bacuse i don't get what it means.. please help me ! :
"which amounts up to £1 cannot be paid exactly with fewer than 6 coins?"
please help... thankyou
I'm not familiar with the denominations of this currency, but if the question were in dollars, I would be looking for any amount under a dollar that needed six or more coins to make it. For instance, 92 cents would require 3 quarters, a dime, a nickel, and two pennies. That's 7 coins, so 92 cents would be one of my answers.
Hope that helps!
THANKYOU AMY..i know how to do it now ! thanks very much !
Your UK coins are 1, 2, 5, 10, 20 and 50 pence. Anything ending in eight or nine pence requires 3 coins plus whatever it takes to make a multiple of ten pence. 88, 89, 98 and 99 pence require six coins. For example, you can make 88 with 50 + 20 + 10 + 5 + 2 + 1
