solve these step by step​

Answer 1

Answer:

Question 1 and 2-Done.

Question 3-Sorry I do not know the answer.

Step-by-step explanation:

Question 1-

Let 'x' be the unknown number.

Given,

• -2-x=3/8
• -2=3/8+x(-x is transposed to the other side)
• -2-3/8=x(-3/8 is transposed to the other side)
• -2/1-3/8=x

LCM=8

• -2(8)/1(8)-3/8=x
• -16/8-3/8=x
• (-16-3)/8=x
• -19/8=x
• x=-19/8

Hence, proved.

Question 2-

Let the unknown number be 'x'.

-5/8×x=3/4

• -5x/8=3/4
• -5x=8(3)/4[1/8 is transposed to the other side]
• 4(-5x)=8(3)[1/4 is transposed to the other side]
• -20x=24
• x=24/-20[-20 is transposed to the other side]
• x=-6/5
• Hence, proved.

Question 3-

Sorry but I forgot how to do this and so I am really sorry.

Answer:

thank you so much.. sorry 3 number i don't know
