This is the problem Dan says 3/5 Is the same as 3.5. Is he correct? Explain

lesya692 [45]

Answer:

He is not correct

Explanation:

The first number is $\frac{3}{5}$

We can note that the numerator is less than the denominator. This means that the given fraction is less than 1

In decimal form, $\frac{3}{5}$ is equal to 0.6

The second number is 3.5

We can note that this number is greater than 1.

This means that the two numbers are not equal

Hope this helps :)

F) m(4+p) +p(3 + m)

ipn [44]

$\bold{\huge{\pink{\underline{ Solutions }}}}$

Here, we have to expand the given expressions and simplify each one of them

<h3>Solution 1 :-</h3>

$\bold{m(4 + p) + p( 3 + m) }$

$\sf{4×m + m× p + p×3+ m × p}$

$\sf{4m + mp + 3p + mp }$

$\bold{\red{ 2mp + 4m + 3p}}$

Hence, Your answer is 2mp + 4m + 3p

<h3>Solution 2 :-</h3>

$\bold{4r(3+ 4p) + 3p( 8 - r) }$

$\sf{4r× 3+ 4r × 4p + 3p× 8 - 3p × r}$

$\sf{12r + 16rp + 24p - 3rp }$

$\sf{12r + 24p + 13rp }$

$\bold{\red{13rp + 24p + 12r }}$

Hence, your answer is 13rp + 24p + 12r

<h3>Solution 3 :-</h3>

$\bold{(3 + 2h)(5 + 3h )}$

$\sf{3(5 + 3h) + 2h(5 + 3h }$

$\sf{15 + 9h + 10h + 6h² }$

$\sf{15 + 19h + 6h²}$

$\bold{\red{6h² + 19h + 15}}$

Hence, your answer is 6h² + 19h + 15

<h3>Solution 4 :-</h3>

$\bold{(3 + 4y)(5y - 1 ) }$

$\sf{3(5y - 1 ) + 4y(5y - 1) }$

$\sf{15y - 3 + 20y² - 4y }$

$\sf{11y - 3 + 20y²}$

$\bold{\red{20y² + 11y - 3 }}$

Hence, your answer is 20y² + 11y - 3

<h3>Solution 5 :-</h3>

$\bold{(2n - 3p )(3p - 2m ) }$

$\sf{2n(3p - 2m) -3p(3p - 2m) }$

$\sf{ 6np - 4nm - 9p² + 6mp }$

$\bold{\red{- 9p² - 6mp - 4nm + 6np }}$

Hence, your answer is - 9p² - 6mp - 4nm + 6np
