Which explains whether the sum of 0.52 + 0.61 is less than or greater than 1?

(1 point)
The sum is less than
• 1 because both decimals are less than 1.
The sum is less than
• 1 because the sum does
not completely shade one hundredths grid.
The sum is greater than
O 1 because the sum shades
more than one hundredths grid.
The sum is greater than
1 because any two
• hundredths decimals added together is greater than one.

To determine whether the sum of 0.52 and 0.61 is less than or greater than 1, we can simply add the two decimals together:

0.52 + 0.61 = 1.13

Now we can assess the options given:

  1. "The sum is less than 1 because both decimals are less than 1." - This is incorrect; though both decimals are less than 1, their sum exceeds 1.

  2. "The sum is less than 1 because the sum does not completely shade one hundredths grid." - This is also incorrect; the sum exceeds 1.

  3. "The sum is greater than 1 because the sum shades more than one hundredths grid." - This is correct; since 1.13 exceeds 1, it indeed would shade more than one whole hundredths grid.

  4. "The sum is greater than 1 because any two hundredths decimals added together is greater than one." - This statement is not accurate for all cases; while 0.52 + 0.61 is greater than one, this is not a universal rule for all hundredths decimals.

The best explanation is option 3: "The sum is greater than 1 because the sum shades more than one hundredths grid."
