Final answer:
To sketch the minimal collection for a decimal, we can use place value blocks like base ten pieces. The number can then be written as a fraction using the place value of the decimal. The fraction is 35/100 or 7/20.
Step-by-step explanation:
To sketch base ten pieces to show the minimal collection for each decimal, we can use place value blocks. Let's take an example of the decimal 0.35. We can sketch 3 tenths and 5 hundredths using base ten blocks, where each block represents one tenth or one hundredth. So, the sketch would have three tenths rods and five hundredths blocks.
To write the number as a fraction, we use the place value of the decimal. In the case of 0.35, the 3 is in the tenths place and the 5 is in the hundredths place. Therefore, the fraction representation would be 3/10 + 5/100, which can be simplified to 35/100 or 7/20.
