Answer 1

Answer:

2520

Step-by-step explanation:

28/100×4500=45×28=1260

45/100×2800=45+28=1260

1260 + 1260 = 2520

Answer 2

Question:

• Evaluate: 28% of 4500 + 45% Of 2800

Solution:

28% of 4500:-

$: \longmapsto \: \sf{ \dfrac{28}{100} \: \times \: 4500 }$

$: \longmapsto \: \sf{ \dfrac{28}{ \cancel{100}} \: \times \: \cancel{4500 }}$

$: \longmapsto \: \sf{28\times 45}$

$: \longmapsto \: \red{\boxed{\sf{1260}}}$

45% of 2800:-

$: \longmapsto \: \sf{ \dfrac{45}{100} \: \times \: 2800 }$

$: \longmapsto \: \sf{ \dfrac{45}{ \cancel{100}} \: \times \: \cancel{2800 }}$

$: \longmapsto \: \sf{28\times 45}$

$: \longmapsto \: \red{\boxed{\sf{1260}}}$

Now adding both of them,

$: \longmapsto \: \sf{1260 \: + \: 1260}$

$: \longmapsto \: \pink{\boxed{\bf{2520}}}$
