Priya is given the following Prime Factorisations: 45=3 x 3 x 5 and 105 = 3 x 5 x 7 She uses this information as follows:
The HCF of 45 and 105 is 15 and the LCM of 45 and 105 is 105.
Priya is wrong. What mistake has she made?

answers

105= 5×5×5

Step-by-step explanation:

priya is wrong because 105 factorism is 5×5×5

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
