Saira has 75 pencils. Her teacher has asked her to divide them between two
pots. Saira says, ‘I won’t be able to do it.’ Is she right? Explain why.
Yes, she is right. 75 is an odd number so if it is divided between two pots
there will be one left over. We know 75 is an odd number because the ‘ones’
digit is a 5.
