Answer:
52
Step-by-step explanation:
you would divide to salve this problem:
520÷10=52
or you could just move the decimal one place to the left because we are dividing by 10:
520÷10=52
520.0 becomes 52.00
You can use the fact that the adding something t times is equal to multiplying it with t.
There are 52 tens in 520.
Let the number to be expressed is 'b' and we've to express it as sum of 'a' then let we need to add 'a' t times to get b. Thus,
[tex]a + a + ... + a\text{\: (t times)} = b\\a \times t = b\\\\\text{Dividing by a on both sides}\\\\\dfrac{a \times t}{a} = \dfrac{b}{a}\\\\t = \dfrac{b}{a}[/tex]
Since we've to express 520 in terms of addition of tens, thus
a = 10, b=520
Thus,
[tex]t = \dfrac{b}{a} = \dfrac{520}{10} = 52[/tex]
Thus, there are 52 tens in 520.
