25x13= ____twenty fives
___twenty fives + ____ twenty fives
= (____x25)+(___x25)
=_____+_____
=_______
13 = 10 + 3
so
25x13= ____twenty fives
10 twenty fives + 3 twenty fives
= (10x25)+(3x25)
= 250 + 75
= 325
or, even easier, since 4x25=100
12x25 + 1x25
= 300 + 25
= 325
I am also kind of flummoxed but perhaps they just want to teach conversion from words to symbols
25x13= ____twenty fives
maybe 25x13= thirteen twenty fives = 325
thirteen ___twenty fives + thirteen____ twenty fives
= (13____x25)+(13___x25)
=__325___+___325 __
=___650____
To solve the multiplication problem 25x13, we can break it down into partial products.
First, let's write the number 13 as a sum of its place values: 10 + 3.
Then, we can use the distributive property of multiplication to solve each partial product.
Partial product 1:
25 x 10 = 250
Since we are multiplying by 10, we can simply add a zero at the end of 25.
Partial product 2:
25 x 3 = 75
Multiply 25 by 3, which gives us 75.
Next, we add the two partial products together.
250 + 75 = 325
Therefore, 25x13 = 325.
Let's fill in the blanks based on the explanation above:
25 x 13 = __10 twenty fives + __3 twenty fives
= (___ x 25) + (___ x 25)
= _____ + _____
= _______
