Given that 35.8 x 4.23= 151.434<br>write down a division sum with an answer of 423.​
Nina [5.8K]

Answer:

  151434/358 = 423

Step-by-step explanation:

Every product with non-zero factors can be written as an equivalent division relation.

  a·b = c   ⇒   a = c/b

Here, we have 35.8 × 4.23 = 151.434. This can be written as the equivalent ...

  4.23 = 151.434/35.8

We can multiply this by 100 to get a division relation with a quotient of 423:

  423 = 15143.4/35.8

If we want, we can move the decimal points another place to the right to get ...

  151434/358 = 423

mariarad [96]

Answer:

7 1/17 shifts

That would be 7 1/2 divided by 1 1/16

=  15/2 / 17/16

= 15/2 * 16/17

= 15 * 8  /  17

=  120/17
