The number equivalent to 7 tens and 20 ones is 90. The number equal to 5 tens and 13 ones is 63. We determine these numbers by multiplying the tens by 10 and adding the ones. ;
The student is asking about converting numerical expressions involving tens and ones into standard numerical form. To find the number that is the same as 7 tens and 20 ones, we multiply 7 by 10 (since there are 10 ones in a ten), giving us 70. Then, we add 20 ones to get the final number. So, 7 tens and 20 ones equal 70 + 20 = 90.
Similarly, to find the number that is the same as 5 tens and 13 ones, we multiply 5 by 10 to get 50, and then add 13 ones. Therefore, 5 tens and 13 ones equal 50 + 13 = 63.
The number that is the same as 7 tens and 20 ones is 90, and the number equivalent to 5 tens and 13 ones is 63.
