Hint: We need to compare 1.5 and 1.50. We should see the position of the decimal point.
Complete step-by-step answer: The numbers are 1.5 and 1.50. Ones part of 1.5 and 1.50 are equal. Tenths part of 1.5 and 1.50 are also equal. Hundredths part of 1.5 and 1.50 are also equal. The ‘0’ after the decimal point (in this case) doesn’t contribute to the value of the number. $\therefore $ 1.5 = 1.50 So, this is your required answer.
Note: In this type of question always compare ones, tenths and hundredths part, you will get your answer. The positioning of numbers like 0 is important like 1.5 or 1.50 or 1.500000 are all the same but they are not the same as 1.05 or 15.0.
