Answer key · Set A
Reading a big number
1four thousand seven hundred six Say the thousands group, then the word thousand, then the last three digits: four thousand seven hundred six.
23971 3 goes in the thousands group and 971 in the ones group: 3,971.
35 1,515 has 1 thousand, 5 hundreds, 1 ten and 5 ones.
47,803 7 thousands, 8 hundreds, no tens and 3 ones: 7,803. A zero holds the tens place.
5True 56,214 has 5 ten-thousands and 6 thousands, so the 6 is worth 6,000.
6< Both have 9 thousands and 9 hundreds. Compare the tens: 3 tens is less than 4 tens, so 9,934 < 9,941.
7107695 The thousands group is 107 and the ones group is 695: 107,695.
820000 20,910 has 2 ten-thousands, 9 hundreds and 1 ten, so the missing part is 20,000.
9> 366,786 has 6 digits and 60,555 has 5 digits. The number with more digits is greater.
102, 1, 4, 3 4,076 and 4,706 have 4 digits, so they are the smallest. Then 40,706 and 47,060 have 5 digits.
11False The ones group is 400, which reads four hundred. So 8,400 is eight thousand four hundred.
