26 will be my guess....considering the fact that you have 7 groups of 3 ...7x3= 21....you have 5 left over. 21+5 = 26
If You Put Me Into 7 Equal Groups With 3 In Each Group And 5 Are Left Over, What Number Am I?
The problem would be set up 7 * 3 + 5. This is because you need seven groups of three and there are five more. Therefor, the answer is 26.
Draw a picture of what you did
26 is the answer. 7 groups *3 and 5 are left over i.e 21+5 = 26
