Answer:
Step by step explanation: OK so your question is 26.35×21.5 so that is pretty easy but if you do not know that you are in the right place so what you’re gonna do is if you have a calculator then you need to take that out if you don’t then I’m going to need a piece of paper now for me it’s easy because I have a calculator and you can find a calculator on your iPad your phone etc. but yeah so you’re gonna type in 26.35 Times 21.5 now I want u do that on your own once you type in those numbers you’re going to hit the = and it’s that simple and you’ll then get your answer so I hope that helped you to learn how you multiply those the numbers.
