the mixed number one and one-fourth = 1.25 --> terminates at 5 the mixed number one and one-third = 1.333333.... the decimal one and two tenths = 1.2 -->terminates at 2 the decimal one and three tenths = 1.3 --> terminates at 3 ------ Each of the options has the integer 1 so move to the tenths place to compare. We see 2, 3, 2, and another 3. Looking for the smallest number of the four, look at the two options with 2 in the tenths place. 1.25 --> terminates at 5 1.2 -->terminates at 2 Move to the hundredths place. Compare 1.25 and 1.2. Recall that 1.2 = 1.20 so compare 5 to 0. Zero is smaller and the number 1.2 is the smallest. the decimal one and two tenths = 1.2 --> answer
