In a day a factory manufactures 45,150 buttons. Making one snowman requires 10 buttons. How many snowmen can be created using all the buttons the factory makes? Have a think
Each snowman is 1 group of 10 45,150 10 = 4,515 snowmen TTh Th H T O That means we need to find how many groups of 10 there are in 45,150! 10 10 10 10
In December, 3,427 snowmen are created but 1,863 melt. In January, another 2,441 snowmen are created but some melt again. At the end of January there are 1,558 snowmen left. How many snowmen melted in January? Have a think

On a street there are 100 houses, numbered 1 to 100 Some of the houses create snowmen. All the houses which create snowmen have numbers which are prime numbers. How many snowmen are created on the street? Have a think ?

Making one snowman requires 10 buttons. How many buttons are needed to make all the snowmen on the street? Have a think 10 25 = 250 buttons
The world record for number of snowmen built in an hour is 2,036, set in Akabira in Japan on 28 February 2015. During the world record, 612 more snowmen were built by children than adults. How many snowmen were built by adults? 712 snowmen were built by adults Have a think C 612 712 612 2,036 1,424 712 A 1,424 2 = 712
In the first hour 2,036 snowmen are built. As the snowmen builders become tired, they build 46 fewer snowmen each hour. How many snowmen will they have built after 3 hours?
