Add $3.75+$4.89
how you write a subtraction word problem related to this addition word problem Ms Sue?
Decimals in Grade 3 addition?
3.75
4.89
--------
8.64
or perhaps regrouping it into powers of ten
3*1 + 7*.1 + 5*.01
4*1 + 8*.1 + 9*.01
---------------------
7*1 + 15*.1 + 14 * .01
which is
7*1 + 16*.1 + 4 *.01
which is
8*1 + 6*.1 + 4*.01
which is
8.64
Meg went into the store with $8.64 in her pocket
She spent $4.89 on toys.
How much did she have left to buy candy?
how you find the solution to your subtraction problem without doing any calculation, Damon?
explain
You would subtract since it said how many left.
To find out how much Meg spent in total, we need to add the amounts she spent on candy and toys. Instead of doing the calculation, we can use a mental strategy called "compatible numbers" to estimate the answer without actually performing the math.
First, round each number to the nearest whole number or a number that is easier to work with mentally. In this case, we can round $3.75 to $4 and $4.89 to $5.
Next, add the rounded numbers together. $4 + $5 = $9.
Therefore, based on this estimation, Meg spent approximately $9 in total on candy and toys.
