Write the place value of the underlined digit and round each number to the place of the underlined digit plus name the place val
mylen [45]
Each number after the decimal goes in this order:
tenth
hundredth
thousandth
1. Looks like it's under the second number after the decimal. This would be the hundredth. The number after it is less than 5 so you would round down and keep the number 7, which makes 0.67
2. Being under the first number after the decimal, it would be the tenth. The number 8 is higher than 5 so you need to round the 2 up to three, making it 4.3
Do you think you could solve the rest or would you like more examples?
