Can anyone help me solve these questions, the sixth grade is in a hurry!!!!

8/25 kg = (320) g 4 and 1/5 = (21 5) square decimeter 3/5 m = (60) cm.

2.Judgment. Two identical wires, one used 1/5, the other used 1/5 meters, and the remaining wire (?

Well, I don't know what I want to say about this question? It's not over......

3.Playing True or False 2/5 of the number A must be smaller than 5/6 of the number B ---False).

Multiply a natural number (except 0) by 7/9 and the product must be less than this natural number ---wrong).

The number A is 30, and the number B is multiplied by 30 (1+2/5) means that the number A is 2/5 more than the number B ---false).

Problem Solving 1What is the area of a parallelogram plank, 8/9 meters long at the bottom and 3/4 of the bottom and 3/4 of the low?

Height = 8 9 3 4 = 2 3 meters.

Area = 8 9 2 3 = 16 27 square meters.

2.The school has paved a 400-meter-long circular runway, and 120 meters have been paved, how many meters is exactly 2/5 of the total length?

Two-fifths of the total length = 400 2 5 = 160 meters.

160-120 = 40 meters.

A: At 40 meters of the shop is exactly 2/5 of the total length

Amount (o)....Is this a sixth-grade question?

One. 2.(meters in words) 420 II. It is not possible to compare three. Four. 8 9 3 4=2 3 2 3 8 9=16 27 V. 400x2/5=160 160-120=40

Are you stunned that you don't have hands, this is too simple, wow.

Great circle diameter = diagonal of square = 10

Square area = square of the diagonal 2=50

The diameter of the small circle = the length of the sides of the square.

The radius of the small circle = the side length of the square is 2

Small circle area = * (square side length 2) square = * square side length square 4 = square centimeters.

The diagonal of the square is the diameter of the circle 10 cm, then its side length is (10 2 2) = 5 2 cm.

And the diameter of the small circle is equal to the length of the sides of the square, so the area of the small circle is *(5 2 2) 2=25 2 square centimeters.

Square diagonal 10 cm.

The side length of the square is 10 in diameter

Small circle area = adopt it o( o....

Area of the Great Circle =

Square area = 10 * 100 157

The area of the small circle = (10*100 157)*157 200=5
